In low visibility conditions, the tower controller working positions are provided with Dynamic Virtual Stop Bars (VSB) to improve low visibility operations and enhance controllers' situational awareness. Virtual Stop Bars can be used by the controller to reduce block-sizes once procedural control applies. Additional controller safety nets will be available to indicate violations of Stop Bars (including Dynamic Virtual Stop Bars) and to monitor aircraft for any kind of unauthorized movement (Watch Dog).
